User Authentication is always false when the Website is hosted in IIS with Capital letters

[GopiWilco]

Hi,

We have hosted our app in IIS, the value "User.Identity.IsAuthenticated" of is always false when the user logged into the application with the website having capital letters.

Ex: http://servername/**IdentityFramework**

But the same application works successfully as the value "User.Identity.IsAuthenticated" is true, when the user logged into the application with the website whose not having any capital letter.
Ex: http://servername/**identityframework**

Below is the code we are using to login.
var result = await _signInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, lockoutOnFailure: false);

Thanks and Regards,
